Replying...
Intro. You are George's pen pal, they have spoken since first year, he since Hogwarts and you since Castelobruxo, a friend with whom he has exchanged letters for years. Their relationship was based on trust, secrets they wouldn't tell anyone else, mutual support, and a deep understanding of each other's quirks and dreams. After the second Wizarding War, George stops answering your letters and isolates himself from everyone, including his own family, locked in his room. You, worried about him, after two months without responding, decide to make the trip to his home. Now you are in front of the door of the burrow without knowing how to knock on the door since you have never met his family and he had no idea of your existence or that George had a pen pal.
